How to redirect HTML inside a dialogbox

[Oscar]

Hi all,

I'm new at GWT and I'm trying to create a dialogbox that shows a
website from an external URL. I would also like that when the user
clicks a link, the content generated appears inside the same
dialogbox.

Right now when the user clicks on a link it redirects to a whole new
page as the user clicks to an HTML link.

I would like to do this without having to have access to the HTML code
from the server side.

Is it possible?

I think you may be able to put an iframe (gwt Frame) inside a
DialogBox and have that work, I haven't done this myself but in theory
I think it should work.

Hi jhulford,

Thanks for your answer!

What you say works great for most pages although when the page wants to open a new window this is opened in a new window/tab in the browser. Is there a way to capture these events and avoid opening a new page?

[jhulford]

You should be able to add a click handler to the anchor and call
preventDefault() on the ClickEvent passed to it to prevent the default
page opening action of the anchor tag.

Hi again!

Thanks for your reply.

If I am understanding it right, I should use the anchor for the links contained inside the iframe, right?

The thing is that I don't have access to the embedded content. I want to show an external website inside the iframe but I don't want it to send users away from my site.

Is it possible?

I think you're on a bit of a fools errand here and doing something
that's going to greatly annoy the users of your site - especially now
that tabbed browsing is ubiquitous. I'd definitely not use your site
if you broke links to external pages like that for me.

Hi jhulford,

Thanks again for your time,

I agree that the embedded site should be able to open a new tab/window. What I don't want is the iframe to have access to the parent.

I guess that what I'm trying to do is something like a sandboxed iframe. Nonetheless, when I try to use sandboxed iframe with Firefox (5.0) it just ignores the sandbox  attribute.

Would there be a way to make it work?
